CHARLES E. HITCHINGS, OF NE\V YORK, N. Y.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 3%0,'716, dated April 27, 1886. Application filed March 3, 1886. Serial X0. 193,774. (No modeh) .To aZZ whom it may concern.-

Be it k nown that I, CHARLES E. HITCHINGS, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Apparatus for Operating Pivoted Sashes, of which the following is a specification.

My invention is more particularlyintended for operating the pivoted sashes which are employed in the roofs and sides of greenhouses, but may be also embodied in apparatus or sash-workers for operating any other I pivoted sashes which are not readilyaccessible. Greenhouse sashes are commonly operated through arms carried by a rock-shaft, and with this rock-shaft is connected, by suit able gearing, an operating-shaft extending to a readily-accessible point. This gearing employed to connect the two shafts may advantageously consist of a gear-segment on the rock-shaft and a wormor screw carried by the operating-shaft. \Vhen apparatus of the same pattern is employed for operating either the roof-sashes or the side sashes of a greenhouse, the worm and operating-shaft must stand at different angles relatively to the rock-shaft carrying arms which are connected with the sashes, and it is often desirable to arrange the gearing and operatingshaft at different dis tances from a rafter or beam or post to which is attached a hanger whereby the apparatus is supported.

The object of my invention is to provide a simple means whereby the operating-sh aft an d worm or screw may be adjusted at different angles relatively to the rock-shaft and its arms, and whereby the gear-segment and worm and operatingshaft may be arranged at any desired distance from a rafter, beam, or post to which the apparatus is attached. In apparatus of this class the hanger, which is attached to a rafter, beam, or post, has commonly had attached directly to it, or formed directly with it,an arm which carries the bearing for the operating-shaft, and according to my invention I provide a long sleeve or tube, within which the rock-shaft is journaled, and which is provided with an arm carrying a bearing for the operating-shaft, and I secure this sleeve in the hanger by means of a setscrew or otherwise, so that it may be conveniently turned therein or adjusted axially in the hanger, as may be desired.

In the accompanying drawings, Figure 1 represents a sectional view of a portion of the roof of a greenhouse, including an elevation of my improved sash-operating device. Fig. 2 is a sectional view of a portion of the apparatus in a plane parallel with the rockshaft carrying the arms which are connected with the sash, and upon a larger scale than Fig. 1; and Figs. 3 and 4 are respectively a side view and a plan of portions of the apparatus upon the same scale as Fig. 2.

Similar letters of reference designate corresponding parts in all the figures.

A designates a sash, pivoted at its upper edge, a, and which is moved to open and close it by means of rods 1), extending from arms I), and attached to its lower edge. The arms I) are carried by a rock-shaft, B, and this rock shaft may be turned through suitable gearing connecting it with the operating shaft 0, which is here represented as vertical. The gearing here shown consists of a gear or worm segment, 13, on the rock-shaft B, and a worm or screw, 0, on the operating-shaft G.

D designates a long sleeve or tube, within which the rock-shaft B has a bearing, and which is itself supported by a hanger, E, adapted to be secured to a rafter, A, or other beam or post. The sleeve or tube D is pro vided at its outer end with an arm, D, carrying a bearing, d, for the operating-shaft 0. As here represented, the extremity of the arm D is forked, thereby forming two bearings, d, for the operatingshaft C and a space for the worm 0 between them.

The sleeve or tube D is adj ustably secured by a set-screw, e, in the hanger E, and when this screw is loosened the sleeve or tube D may be turned in the hanger E, or may be slid axially therein, and by either of such movements the position of the arm D, carrying the bearing for the operating-shaft C, will be correspondingly changed. As here represented,the roclrshaft B is held in proper position lengthwise of the sleeve or tube D by a collar, b, on the shaft bearing against one end of the sleeve or tube, and the geansegment B bearing against the other end thereof.

From the above description it will be readily understood that by turning the sleeve D the position of the arm D will be changed so as to hold the operating-shaft O at any desired angle relatively to the rock-shaft, and by sliding the sleeve or tube D axially in the hanger E the arm D is adjusted to difi'erent positions more or less distant from a rafter or beam to which is secured the hanger E.

As here represented, the lower end of the shaft 0 is supported in a bearing, 0, and said shaft may be operated by a crank or handle, U applied to its lower end.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-
